HEAT WAVES IN INDIA: LIFE AND DEATH, TEMPERATURES OVER 50°C (122°F)

HEAT WAVES IN INDIA

average annual temperature

India experienced its worst heat wave in 50 years in May 1998. More than 2,500 people were killed. Global warming is believed to have been involved. Temperatures reached 51° C (123°F) and killed 3,000 people in India in 1998 as a whole. In June, 1994 temperatures soared to 49.5 ° C (121° F) in Rajasthan, leaving more than 400 people dead from heat related illnesses. One six-year old girl died of a heat stroke walking from the village bus stand to her rural hut. A construction worker told the Washington Post, "It is especially difficult for laborers. Sometimes everything goes hazy before my eyes. I get dizzy. I constantly have to keep watch on myself." At the same time, New Delhi thought it was going through a cold spell when temperatures dropped to 37° C (98°F) . Coca Cola got into trouble when it ran an ad campaign during hot spell which read "Thank God for the heat wave."

The India government said the heat had killed 3,500 people from 2015 to 2019. A heat wave in early summer of 2003 left more than 1,300 people dead, many from sunstroke and dehydration. Among the areas hardest hit were the southern state of Andhra Pradesh, where temperatures reached 49°C (120°F) and more than 1,200 people died. Temperatures reached 43° C (109° F) in Calcutta. The heat wave finally dissipated when the monsoon rain arrived, In 2002, a similar heat wave killed more than 1,000.

As global and local temperatures have risen, heatwaves have become regular occurrances in India — particularly in May and June before the onset of the monsoons. Describing a heat wave in May 2020, AFP reported: India is wilting under a heatwave, with the temperature in places reaching 50°C (122°F) and the capital enduring its hottest May day in nearly two decades. The hot spell is projected to scorch northern India for several more days, the Meteorological Department said, "with severe heat wave conditions in isolated pockets". Met officials said Churu in the northern state of Rajasthan was the hottest place on record at 50°Cs, while parts of Punjab, Haryana and Uttar Pradesh sweltered in the high 40sC (110sF).. Parts of the capital, New Delhi, recorded the hottest May day in 18 years with the mercury hitting 47.6 Celsius. [Source: AFP, May 27, 2020]

The country of 1.3 billion people suffers from severe water shortages with tens of millions lacking running water — to say nothing of air conditioning. Parts of Delhi and elsewhere regularly see scuffles when tankers arrive to deliver water. In 2019, Chennai made international headlines when the southern city ran out of water entirely. During the 2020 heatwave, the BBC reported: The Indian capital, Delhi, saw temperatures rise to 47.6° C (117.7°F). The severe heatwave conditions occurred as thousands of migrants are walking on the highways after fleeing cities to try and go back to their villages. Many are walking with little food and water, and will be among the most exposed to the weather. In addition to that, the heatwave has impacted efforts to combat swarms of locusts that are destroying crops in parts of the country, including Rajasthan. Huge swarms of desert locusts, have destroyed nearly 50,000 hectares (125,000 acres) of crops across western and central India, and may enter Delhi in coming days. More than 100 workers are battling the insects, using vehicle-mounted sprayers, pesticides and drones in the searing heat.

Living with High Heat in India

Dhruv Khullar wrote in the The New Yorker: I have family in Delhi, and have visited regularly over the decades. Each year has always felt hotter than the last. But the heat wave [in 2022], was unprecedented in its severity, duration, and geographic expanse. Across much of northern India, where more than a billion people live, temperatures have regularly soared past 43.3°C (110°F)and slightly lower temperatures have often combined with very high humidity—a dangerous combination. “The heat is rising rapidly and much earlier than usual,” Prime Minister Narendra Modi said, in April 2022. “Fire has broken out in many forests, historical monuments, and hospitals.” Indians who work outside—about half the population—have sometimes had to stop in the afternoons, relinquishing their wages; schools and businesses have had to adjust their hours or shut entirely; and farmers have seen their crop yields drop by a third or more. [Source: Dhruv Khullar, The New Yorker, July 25, 2022]

Only eight per cent of Indians have air-conditioning, and many lack reliable electricity, a situation that limits their use of fans and other cooling devices...”It didn’t use to be this hot,” Saira, the woman in a poor area of Delhi said, “Before, it felt like it was possible for humans to work the landfill.” Now, because of the heat, they tried to stay out of the sun. “If you see five hundred people working there right now, you’ll see at least two thousand people up there at night,” she said. We eat up there, sleep up there sometimes,” another worker added.

Hema, a thin woman in a purple sari, sat on the stairs. “When the sun hits, it feels like your body is on fire,” she said. “I drape a shirt over my head—that makes it feel even hotter. When we come back home, our heads feel like they will explode. We take water with us, but it’s boiling by the time we can drink it.” The women described headaches, exhaustion, dizziness, rashes, fever. The stench of the landfill—an acrid mixture of excrement and rotting trash—was sickening, they said, but the heat made it hard to tolerate masks. Outside the hut, children kicked a ragged soccer ball. A scrawny dog panted on a mound of refuse. Flies swarmed a heap of dung. We are living,” Saira said. “But we are also dying.”

The Paharganj Mohalla Clinic, in central Delhi, is one of more than a hundred public clinics in the city. Deepika Sharma, the clinic’s doctor, stood in the second room, The clinic was busy, Sharma told me, but not unusually so. She typically sees a hundred patients a day, with each visit lasting about three minutes. As a physician myself—I practice internal medicine at a large academic hospital in New York—I found this pace dizzying to contemplate. On a normal day, I might see fifteen or twenty patients. But Sharma’s task was made easier, she said, by the fact that so many patients had the same problems. Nearly half the people she saw had respiratory issues—such as asthma, bronchitis, and emphysema—which she attributed to the city’s punishing air pollution. (India has among the world’s highest rates of chronic respiratory disease; on the worst days, breathing the Delhi air is equivalent to smoking two packs of cigarettes.) During the heat wave, she said, around a quarter of her patients suffered heat-related rashes, and a fifth presented with signs of dehydration. Inhalers, calamine lotion, oral rehydration salts—these three medications made up the bulk of her prescriptions.

Heatwave across India on April 29, 2022: Temperatures exceeded 42°C in numerous cities across the country; This comes just weeks after India recorded its hottest March since the country’s meteorological department began its records over 120 years ago; This image, produced using data from the Copernicus Sentinel-3 mission, shows the land surface temperature across most of the nation; According to the India Meteorological Department, maximum air temperatures reached 43-46°C over most parts of Rajasthan, Vidarbha, Madhya Pradesh and East Uttar Pradesh; in many parts over Gujarat, interior Odisha; and in some parts of Madhya Maharashtra; Owing to the absence of cloud cover the Sentinel-3 mission was able to obtain an accurate measurement of the land surface temperature of the ground, which exceeded 60°C (140°F) in several areas; The data shows that surface temperature in Jaipur and Ahmedabad reached 47°C (116°F), while the hottest temperatures recorded are southeast and southwest of Ahmedabad (visible in deep red) with maximum land surface temperatures of around 65°C (149°F) ; The map was generated by using the mission’s Sea and Land Surface Temperature Radiometer instrument; While weather forecasts use predicted air temperatures, this satellite instrument measures the real amount of energy radiating from Earth; Therefore, the map shows the actual temperature of the land’s surface pictured here, which is usually significantly hotter than air temperatures

Public clinics refer their sickest patients to public hospitals. One such institution, Civil Hospital, is situated just off a highway in Palwal, a city of a 350,000 people outside of Delhi. Brahmdeep Sindhu, its chief medical officer, said the heat has created a rise in physical, psychological, and social symptoms,” he said. “Heatstroke, dizziness, low blood pressure, dehydration, exhaustion—we are seeing these almost daily.” The hospital was on a main road, and often admitted travellers. “The A.C.s in cars can’t function at such high temperatures,” he said. “The cars become extremely hot. The other day, three passengers came in—one person vomiting, one person with fever, one person so weak he couldn’t move.”

A psychiatrist by training, Sindhu was especially troubled by a surge in psychological distress caused by the heat. “Patients with bipolar disorder, with schizophrenia—they are really struggling,” he said. The Intergovernmental Panel on Climate Change, in its 2022 report, highlighted for the first time the dire mental-health effects of a warming planet: anxiety, grief, stress, post-traumatic stress disorder. In recent years, heat has been linked to a rise in suicides among Indian farmers, whose livelihoods have been imperilled.

High Temperatures Killing More Indians

A study published in The Lancet in October 2022 found that deaths linked to extreme heat in India increased by 55 percent between the periods 2000–2004 and 2017–2021. The study also estimated that exposure to high temperatures resulted in the loss of 167.2 billion potential labor hours in 2021. According to the report, these lost labor hours were associated with income losses equivalent to approximately 5.4 percent of India's gross domestic product (GDP). The findings highlight the growing economic as well as health impacts of rising temperatures.[Source: BBC, October 26, 2022]

Although heatwaves have long occurred in many parts of the country during the summer, researchers and climate experts report that they are becoming more frequent, longer-lasting, and more intense. The annual “Lancet Countdown” report, which examined conditions in 103 countries, found that the March–April heatwave affecting India and Pakistan was about 30 times more likely to occur because of climate change. A separate study by the United Kingdom's Met Office similarly concluded that climate change had made record-breaking heatwaves in northwestern India and Pakistan about 100 times more likely. Without climate change, such extreme temperatures would be expected to occur only once every 312 years. The report noted that extreme heat can directly affect human health by increasing the risk of heat stroke and worsening existing cardiovascular and respiratory conditions. It can also contribute to adverse pregnancy outcomes, sleep disruption, mental health challenges, and higher rates of injury-related deaths, with vulnerable populations facing the greatest risks.

True death tolls are likely much higher than official counts. Dhruv Khullar wrote in the The New Yorker: In 2010, during a heat wave in Ahmedabad, the financial center of the state of Gujarat, officials counted 75 heatstroke deaths during the hottest week—but a later analysis of death certificates revealed that there had been at least 800 more deaths than usual during that time, some 200 of them on a single day. Research has shown that, each day the temperature rises above ninety-five degrees in India, the annual mortality rate increases by three-quarters of a per cent. (In the United States, the rate increases by only .03 per cent.) [Source: Dhruv Khullar, The New Yorker, July 25, 2022]

A study by researchers at the University of Cambridge found that extreme heat poses a threat to about 80 percent of India's 1.4 billion people and that its effects on the country's development are being underestimated. The researchers argued that current measures of climate vulnerability fail to fully account for how rising temperatures hinder progress in reducing poverty, improving health, expanding education, and achieving other development goals. The study noted that climate change, driven largely by the burning of fossil fuels, has increased the frequency and intensity of heatwaves in India.[Source: Sibi Arasu, Associated Press, April 20, 2023]

Heat Wave in India in 2015 Kills 1,100 People

Heatwave across India on April 12, 2022: images, produced using data from the Copernicus Sentinel-3A satellite on April 12, 2022, show a cloudless view (right) and land surface temperature (left) over northwest India during a prolonged heatwave; the rainfall level during the pre-monsoon season in 2022, which started on March 1, reached only 9% of the long-period average (LPA); temperatures exceeding 41°C (106°F)in numerous cities; Experts at the Indian Institute of Technology’s Water and Climate Lab stated that, in recent years, the number of Indian states hit by heatwaves has increased and extremely hot temperatures have become less uncommon; land surface temperature (the temperature of the soil), exceeded 50°C (122°F) in several areas

In 2015, one of India’s deadliest heat waves in recent history caused more than 1,100 deaths and affected large parts of the country. Temperatures remained exceptionally high for several weeks, with New Delhi recording highs of about 45°C (113°F). In parts of eastern and central India, temperatures climbed even higher, reaching nearly 48°C (118°F), while some locations reported temperatures above 50°C (122°F). The extreme heat was intense enough to soften and damage road surfaces in some areas. [Source: Adam Chandler, The Atlantic, May 27, 2015]

Most of the fatalities occurred within a short period as the heat wave intensified. High humidity in many regions increased the danger by making it more difficult for the human body to cool itself through sweating. The effects were particularly severe for millions of people who lacked reliable access to electricity, air conditioning, or other means of protection from the heat.

Meteorologists linked the prolonged heat wave to changes in weather patterns over the Bay of Bengal. The departure of cloud systems and winds that normally bring pre-monsoon showers allowed hot, dry conditions to persist across much of the country. As a result, temperatures remained well above normal for an extended period.

Although heat waves occur regularly during India’s summer season, the 2015 event was unusually deadly because of its duration and intensity. Frequent power outages, limited infrastructure, and the large number of people who depend on outdoor work for their livelihoods increased the risks. Many laborers continued working despite suffering from symptoms such as headaches, dehydration, and heat exhaustion.

Older adults, low-income residents, and people working outdoors were among the most vulnerable. Hospitals in severely affected states, including Telangana, reported large numbers of patients suffering from heat-related illnesses. Many of those admitted were elderly individuals or people who spent long hours exposed to direct sunlight.

The heat wave also disrupted daily life and education. Authorities in New Delhi ordered schools to begin their summer vacations early as temperatures continued to rise. Officials warned that the extreme conditions could persist for several more weeks before the arrival of seasonal rains brought relief to many parts of the country.

Temperatures Reach 51°C (124°F) During the Heat Wave of 2016

India experienced an intense and prolonged heat wave during the summer of 2016. Temperatures rose across large parts of the country, particularly in the western, central, and northern regions. The heat wave developed against the backdrop of two consecutive years of weak monsoon rainfall, which had already left many areas facing severe drought conditions. As a result, high temperatures were accompanied by widespread water shortages.[Sources: The Guardian, May 4, 2016; Muneeza Naqvi, Associated Press, May 21, 2016; Rishi Iyengar, Time, June 6, 2016; Nida Najar and Hari Kumar, New York Times, May 20, 2016]

The most extreme temperatures were recorded in the state of Rajasthan. On 19 May 2016, the desert city of Phalodi reached 51°C (123.8°F), the highest temperature ever officially recorded in India at that time. The previous national record of 50.6°C (123°F), set in Alwar in 1956, was surpassed. Other parts of Rajasthan, Gujarat, and Madhya Pradesh also experienced temperatures exceeding 47°C (116.6°F).

The heat wave persisted for more than two months in some regions. Even as the southwest monsoon began arriving in southern India, many northern and western areas continued to endure extremely high temperatures. Meteorologists warned that severe heat would continue until widespread monsoon rains arrived. Forecasts indicated that temperatures would remain well above normal across much of the country.

The extreme conditions were intensified by drought. Rivers, lakes, reservoirs, and groundwater supplies had already been depleted by poor rainfall in previous years. The combination of record-breaking heat and water scarcity created what some experts described as a “double burden” for affected communities. Many rural areas faced both extreme temperatures and a lack of reliable water supplies.

The heat wave reflected broader concerns about increasingly frequent extreme weather events in India. Scientists noted that unusually high temperatures are consistent with global warming trends. Although individual heat waves are influenced by many factors, researchers warned that rising global temperatures could make severe heat events more common in the future. The 2016 heat wave became one of the most notable examples of extreme weather in modern India.

Deaths and Suffering During the 2016 Heat Wave

The prolonged heat wave caused widespread suffering across India and contributed to hundreds of deaths. More than 130 people were reported to have died from heat-related causes and the associated drought during the most severe phase of the event. Many victims were exposed to extreme temperatures while working outdoors. Laborers, farm workers, and other people without access to cooling facilities were especially vulnerable. [Sources: The Guardian, May 4, 2016; Muneeza Naqvi, Associated Press, May 21, 2016; Rishi Iyengar, Time, June 6, 2016; Nida Najar and Hari Kumar, New York Times, May 20, 2016]

Hospitals in affected regions reported a significant increase in patients suffering from heat-related illnesses. Doctors treated large numbers of people for dehydration, heat exhaustion, diarrhea, fever, and heatstroke. In Phalodi, medical facilities saw patient numbers rise sharply during the hottest days. Health officials warned that prolonged exposure to the sun could quickly become life-threatening.

The heat wave placed additional strain on communities already struggling with drought. Crop failures and water shortages affected millions of people across more than a dozen states. Farmers faced declining harvests, dying livestock, and shrinking incomes. Many rural households struggled to obtain enough water for drinking, cooking, and washing.

The effects were particularly severe in drought-stricken regions. Groundwater reserves fell to critically low levels, and many traditional water sources dried up completely. Some residents were forced to travel long distances to obtain water. Others depended on emergency water deliveries organized by government agencies.

The agricultural crisis also contributed to social and economic hardship. Thousands of small farmers left their land in search of work in urban areas. Rural communities experienced declining agricultural production and growing financial stress. The combination of heat, drought, and economic hardship created one of the most challenging summers many residents had experienced in decades.

Impacts of the 2016 Heat Wave in India on Daily Life

The heat wave disrupted daily life across many parts of India. In cities and towns, people altered their routines to avoid the hottest hours of the day. Outdoor activities were reduced, and many residents remained indoors whenever possible. Streets and public spaces were noticeably quieter during peak afternoon temperatures. [Sources: The Guardian, May 4, 2016; Muneeza Naqvi, Associated Press, May 21, 2016; Rishi Iyengar, Time, June 6, 2016; Nida Najar and Hari Kumar, New York Times, May 20, 2016]

Schools were among the institutions most directly affected. Authorities in Delhi ordered all schools to begin mandatory summer vacations earlier than planned because of the dangerous conditions. Similar closures occurred in other parts of the country. Schools were forced to reschedule examinations, lessons, and other activities, disrupting academic calendars.

Travel and transportation became more difficult as temperatures soared. Children often faced long journeys to school in intense heat, while workers commuting across large cities encountered uncomfortable and potentially dangerous conditions. Many people adjusted their schedules to travel during cooler morning or evening hours. Public concern about heat-related health risks increased significantly.

The drought compounded the effects of the heat wave on everyday life. Water shortages affected households, farms, and businesses. In many communities, residents had limited access to clean water for drinking, bathing, and sanitation. Competition for scarce water resources intensified, particularly in regions already suffering from prolonged drought.

Food production and rural livelihoods were also affected. Poor harvests reduced farm incomes and placed pressure on local economies. Livestock suffered from shortages of water and fodder, while milk production declined in some areas. The combined effects of heat and drought created significant challenges for millions of people across the country.

How Authorities Dealt with the 2016 Heat Wave

Government agencies and meteorological authorities issued a range of measures to reduce the risks posed by the heat wave. Severe heat-wave alerts were announced for affected states, including Rajasthan, Gujarat, and Madhya Pradesh. Weather departments regularly updated forecasts and warned residents about dangerous conditions. These alerts helped communities prepare for periods of extreme heat. [Sources: The Guardian, May 4, 2016; Muneeza Naqvi, Associated Press, May 21, 2016; Rishi Iyengar, Time, June 6, 2016; Nida Najar and Hari Kumar, New York Times, May 20, 2016]

Public health officials encouraged people to remain indoors during the hottest parts of the day and to drink sufficient water. Authorities emphasized the importance of avoiding unnecessary outdoor activity and protecting vulnerable groups such as children and the elderly. Public awareness campaigns promoted hydration and other heat-safety practices. These measures aimed to reduce the number of heat-related illnesses.

Hospitals and medical facilities were instructed to prepare for an increase in heat-related emergencies. Many hospitals reserved beds for patients suffering from heatstroke and dehydration. Medical staff monitored vulnerable patients and provided treatment for heat-related conditions. Health services played an important role in responding to the crisis.

Governments also implemented emergency measures to address water shortages. In some of the worst-affected areas, water was transported by train to communities facing severe shortages. Emergency supplies were delivered to drought-stricken regions where reservoirs and groundwater reserves had been exhausted. Authorities worked to maintain access to drinking water despite increasingly difficult conditions.

The heat wave highlighted the need for longer-term planning and adaptation. Officials discussed improvements in drought management, water conservation, and heat-wave preparedness. Some experts argued that school calendars, urban infrastructure, and public health systems would need to adapt to a warmer climate. The events of 2016 demonstrated the growing importance of heat-response strategies in India.

Heat Wave in India in 2022

The summer of 2022 arrived exceptionally early in India, with extreme temperatures beginning to sweep across the nation as early as March. According to meteorological records, the average maximum temperatures for that month were officially documented as the highest in 122 years. This premature onset caught millions off guard, affecting approximately 15 states, including northern regions like Himachal Pradesh that are typically celebrated for cooler, pleasant climates. The unusual duration and early timing underscored a shifting pattern in the region's seasonal transitions. [Source: Alia Shoaib, Business Insider, May 14, 2022; Sudarshan Varadhan, Reuters, May 2, 2022; Sharanya Hrishikesh & Meryl Sebastian, BBC, May 16, 2022; Jibran Ahmad and Sumit Khanna, Reuters, April 29, 2022]

As the summer progressed, northern India bore the brunt of an unrelenting atmospheric pressure system that trapped blistering air over major urban centers. In the capital city of Delhi, temperatures soared to a record-breaking 49.2°C (120.5°F) in various districts, marking the city's fifth distinct heat wave since the spring began. Near the India and Pakistan border, regional indicators predicted that peak conditions would push the mercury close to 51°C (122°F). The persistent meteorological abnormality blanketed states like Haryana, Punjab, Bihar, and Uttarakhand in an inescapable dome of heat.

Senior scientists at the India Meteorological Department attributed the unprecedented crisis to a unique combination of local atmospheric irregularities. A primary driver was the noticeable weakness in western disturbances, which are storms originating in the Mediterranean region that typically bring vital pre-monsoon rainfall. Without these showers, northwestern and central India remained completely dry, while localized anticyclones further compressed and heated the air over western territories. These overlapping atmospheric phenomena successfully prevented any natural cooling mechanisms from developing across the subcontinent.

While local weather fluctuations played an immediate role, climate experts pointed directly to global warming as the fundamental root cause of the intensifying trend. A study published in the medical journal The Lancet concluded that the 2022 heat wave hitting India and Pakistan was made 30 times more likely due to human-induced climate change. Furthermore, researchers noted that urban pollution, black carbon, and heavy dust absorbed sunlight, amplifying regional temperatures. Rapid urbanization and expanding concrete roads trapped this thermal energy close to the ground, preventing the air from cooling even after sunset.

Deaths and Suffering in the Indian Heat Wave of 2022

The prolonged weather extremity took a heavy toll on human life, causing widespread physical suffering across multiple Indian states. Official tallies recorded dozens of immediate heatstroke fatalities within a few weeks, though historical data revealed a much broader and alarming trend. A prominent medical study highlighted that heat-related deaths in India actually surged by 55 percent when comparing recent years to the early 2000s. Vulnerable populations, particularly infants, the elderly, and individuals battling chronic respiratory or cardiovascular illnesses, faced the highest risk of mortality. [Source: Alia Shoaib, Business Insider, May 14, 2022; Sudarshan Varadhan, Reuters, May 2, 2022; Sharanya Hrishikesh & Meryl Sebastian, BBC, May 16, 2022; Jibran Ahmad and Sumit Khanna, Reuters, April 29, 2022]

Healthcare facilities faced immense pressure as a continuous influx of suffering citizens sought emergency medical intervention. Local medical associations reported that clinics were overwhelmed with patients presenting severe symptoms of dehydration, heat exhaustion, and dizziness. Shockingly, up to 70 percent of these daytime patients in certain hard-hit areas were school-aged children suffering from vomiting, diarrhea, and abdominal colic. Doctors warned that prolonged exposure to the blistering daytime environment could rapidly transition into life-threatening organ failure.

The economic burden of the extreme climate fell disproportionately on the shoulders of the working poor and outdoor laborers. Millions of individuals, including construction workers, agricultural hands, and street cleaners, had no financial choice but to work under the blazing sun without protection. This intense exposure resulted in a staggering loss of 167.2 billion potential labor hours across the workforce. The resulting drop in productivity and income translated to an economic loss equivalent to roughly 5.4 percent of India’s total gross domestic product.

Compounding the daily misery, elevated nighttime temperatures meant that human bodies were unable to properly cool down or recuperate after sunset. This continuous thermal stress exacerbated underlying medical conditions and heavily increased out-of-pocket medical expenses for impoverished families. The true danger materialized when extreme high temperatures intersected with soaring humidity, creating hazardous "wet-bulb" conditions. Under these scientifically measured thresholds, the human body loses its natural capacity to cool itself through sweating, making outdoor survival impossible after just a few hours.

Birds Fall from the Skies and Landfills Catch Fire During the 2022 Heat Wave in India

The ecological impact of the 2022 heat wave manifested in dramatic ways, severely threatening local wildlife and urban ecosystems. As intense heat dried up natural ponds, lakes, and traditional watering holes, countless birds fell directly out of the sky due to severe dehydration. In western states like Gujarat, animal rescue trusts reported a ten percent increase in wildlife emergencies, taking in dozens of dropped pigeons and kites every single day. Veterinary surgeons worked tirelessly around the clock, using syringes to inject water into the mouths of exhausted eagles and administering liquid multivitamins. [Source: Alia Shoaib, Business Insider, May 14, 2022; Sudarshan Varadhan, Reuters, May 2, 2022; Sharanya Hrishikesh & Meryl Sebastian, BBC, May 16, 2022; Jibran Ahmad and Sumit Khanna, Reuters, April 29, 2022]

Daily human routines were severely disrupted as cities scrambled to adapt to the hostile ambient environment. Public streets, markets, and tourist destinations like Delhi's Red Fort became completely deserted during peak afternoon hours as citizens sought shade. To protect the youth, authorities ordered all Delhi schools to begin a mandatory early summer vacation, forcing private and municipal institutions to alter their academic calendars. This abrupt closure created administrative nightmares for headteachers, who had to completely cancel or reschedule essential unit tests and cycle examinations.

The extreme weather triggered an unprecedented energy crisis as a billion citizens simultaneously attempted to find relief through mechanical cooling. Electricity demand spiked by over 13 percent nationally, forcing northern states to experience their worst power shortages in over six years. Mountainous tourist retreats like Sikkim and Himachal Pradesh saw electricity requirements jump significantly as visitors fled the sweltering lowlands. This surge quickly exhausted regional utilities, causing widespread power cuts as coal inventories plummeted to their lowest pre-summer levels in nearly a decade.

Dhruv Khullar wrote in The New Yorker: The Bhalswa landfill, on the outskirts of Delhi, is an apocalyptic place. A gray mountain of dense, decaying trash rises seventeen stories, stretching over some fifty acres. On the afternoon of April 26th, Bhalswa caught fire. Dark, toxic fumes spewed into the air, and people living nearby struggled to breathe. By the time firefighters arrived, flames had engulfed much of the landfill. In the past, similar fires had been extinguished within hours or days, but Bhalswa burned for weeks. “The weather poses a big challenge for us,” Atul Garg, the chief of the Delhi Fire Service, said, nine days after the fire began. “Firefighters find it difficult to wear masks and protective gear because of the heat.” A nearby school, blanketed by hazardous smoke, was forced to close. In the end, it took two weeks to extinguish the blaze. The charred bodies of cows and dogs were found in the debris. When I visited, in May, some sections of the landfill were still releasing angry coils of smoke. In the car, I consulted my phone, which told me that it was a hundred and three degrees outside, with thirty-two-per-cent humidity. Still, when I opened the door, I was stunned by the three-dimensionality of the heat. The sun fried my skin but also somehow roasted me from within. I felt as if I’d swallowed a space heater. [Source: Dhruv Khullar, The New Yorker, July 25, 2022]

The compounding effects of the heat wave also inflicted severe damage on the nation’s agricultural output and infrastructure safety. Unexpected temperature spikes heavily impacted the crucial wheat harvest, lowering yields and threatening food security during a period of global supply disruptions. Simultaneously, the extreme dry spell sparked a dangerous increase in fires across agricultural fields, forests, and critical municipal buildings. In New Delhi, a massive blaze erupted at the Bhalswa landfill site, sending toxic plumes of smoke into the atmosphere and forcing nearby neighborhood schools to close.

How the Indian Government Responded to the Heat Wave of 2022

In response to the growing national emergency, top government officials initiated high-level administrative interventions to manage the crisis. Prime Minister Narendra Modi convened emergency online conferences with state chief ministers to coordinate active mitigation strategies. He explicitly instructed regional leaders to formulate comprehensive action plans to combat the premature temperature spikes and protect local economies. Additionally, the federal government mandated immediate fire-safety audits across all hospitals and factories to prevent infrastructure disasters during the dry spell. [Source: Alia Shoaib, Business Insider, May 14, 2022; Sudarshan Varadhan, Reuters, May 2, 2022; Sharanya Hrishikesh & Meryl Sebastian, BBC, May 16, 2022; Jibran Ahmad and Sumit Khanna, Reuters, April 29, 2022]

Meteorological and public health agencies worked together to roll out extensive safety campaigns and early warning systems. The India Meteorological Department frequently issued severe heat wave alerts, accurately predicting temperature shifts to give local populations time to prepare. Health advisories urged citizens to remain indoors during peak afternoon hours and emphasized the vital importance of consistent hydration. Public notices also highlighted traditional coping mechanisms, encouraging people to consume cooling buttermilk and utilize raw mango rub treatments to prevent heatstroke.

Emergency relief operations were deployed on the ground to address the critical shortages of water and medical supplies. Hospitals across vulnerable states were ordered to set up specialized, air-conditioned isolation wards specifically designated for treating heatstroke victims. Non-governmental organizations and animal welfare groups established temporary field clinics to distribute water and medical aid to domestic pets and wild animals. In rural regions where groundwater reservoirs had completely dried up, the central government organized emergency relief by transporting thousands of gallons of water directly to communities via trains.

The severity of the 2022 event ultimately forced authorities to evaluate long-term urban planning and labor policy overhauls. While seasonal bans on outdoor labor during peak hours had been utilized since 2015, experts argued that structural changes were required to build true climate resilience. Urban planners began discussing international innovations in architectural design to prevent modern concrete buildings from trapping internal heat. Moving forward, policymakers emphasized that greening cities, restoring natural water bodies, and restructuring school calendars would be essential steps to survive an increasingly warm future.
